Joakim Zhang 66ce8bfad6 can: flexcan: flexcan_remove(): disable wakeup completely
[ Upstream commit ab07ff1c92fa60f29438e655a1b4abab860ed0b6 ]

With below sequence, we can see wakeup default is enabled after re-load module,
if it was enabled before, so we need disable wakeup in flexcan_remove().

| # cat /sys/bus/platform/drivers/flexcan/5a8e0000.can/power/wakeup
| disabled
| # echo enabled > /sys/bus/platform/drivers/flexcan/5a8e0000.can/power/wakeup
| # cat /sys/bus/platform/drivers/flexcan/5a8e0000.can/power/wakeup
| enabled
| # rmmod flexcan
| # modprobe flexcan
| # cat /sys/bus/platform/drivers/flexcan/5a8e0000.can/power/wakeup
| enabled

Fixes: 915f966642 ("can: flexcan: add support for DT property 'wakeup-source'")

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
